Bipolar Disorder: Clinical Perspectives and Implications with Cognitive Dysfunction and Dementia
R. Lopes,L. Fernandes
Depression Research and Treatment , 2012, DOI: 10.1155/2012/275957
Abstract: Introduction. Cognitive dysfunction as a core feature in the course of bipolar affective disorder (BPD) is a current subject of debate and represents an important source of psychosocial and functional burden. Objectives. To stand out the connection and clinical implications between cognitive dysfunction, dementia, and BPD. Methods. A nonsystematic review of all English language PubMed articles published between 1995 and 2011 using the terms “bipolar disorder,” “cognitive dysfunction,” and “dementia”. Discussion. As a manifestation of an affective trait or stage, both in the acute phases and in remission, the domains affected include attention, executive function, and verbal memory. The likely evolution or overlap with the behavioural symptoms of an organic dementia allows it to be considered as a dementia specific to BPD. This is named by some authors, as BPD type VI, but others consider it a form of frontotemporal dementia. It is still not known if this process is neurodevelopmental or neurodegenerative in nature, or both simultaneously. The assessment should consider the iatrogenic effects of medication, the affective symptoms, and a neurocognitive evaluation. Conclusion. More specific neuropsychological tests and functional imaging studies are needed and will assume an important role in the near future for diagnosis and treatment. 1. Introduction For a long time mild and severe cognitive deficits have been recognized as part of mental disorders. In affective disorders, although initially considered as secondary features related to social or psychological factors, they are now recognized as playing an integral part of the clinical expression [1] and a connection with dementia has also been suggested [2]. More than half of patients with prolonged BPD over 60 years have cognitive deficits [3] and about two-thirds have subjective amnesic complaints [1]. Yet, the recognition of the impact of these deficits on psychosocial and occupational functioning [4–6] and therapeutic compliance (patients often attribute these deficits to medication side effects) is an important feature of BPD [7]. Also, it certainly contributes to an impairment of functional recovery, which even in euthymia is achieved slowly, despite modern symptomatic treatments [7]. In fact, recent reports have documented that some cognitive deficits (processing speed and verbal learning/memory) are independent predictors of functional recovery [6, 8] and also that improvements in neurocognitive status could predict changes in functional outcome [9]. The consideration of cognitive impairment as a
The Starburst Model for AGN: Past, Present & Future
R. Cid Fernandes
Physics , 1996,
Abstract: It is now eleven years since Terlevich \& Melnick first proposed an `AGN without black-holes' model, an idea which since then evolved into what is now called the starburst model for AGN. This model has been the subject of much debate in the last decade, with observational evidence both for and against it further fuelling the controversy. Can we after all these years reach a veredictum on whether starbursts can power AGN? This contribution tries to answer this question reviewing the main achievements of the starburst model, its current status and future prospects.
Relaxation Time Approximation for the Wigner-Boltzmann Transport Equation
Aldo R. Fernandes Nt
Physics , 2015,
Abstract: A quasi-distribution function in phase space (based on Wigner functions) is used to write down the quantum version of Boltzmann equation (Wigner-Boltzmann transport equation). The relaxation time approximation is show to be a good approach when defects are homogeneously distributed and linear response to the external electric field is assumed. An expression for relaxation times based on this formalism is deduced, which consider the dependence in the quantum numbers when confinement effects are important (nanowires and nanosheets).
Efeitos do tempo de freqüência do pré-escolar do Programa Centro de Educa??o e Alimenta??o do Pré-Escolar sobre o desenpenho avaliado pelo "Instrumento II", adicional
Fernandes,José; Gandra,Yaro R.;
Revista de Saúde Pública , 1981, DOI: 10.1590/S0034-89101981000700012
Abstract: the influence of the length of attendance at the ceape program is studied on the cognitive, perceptive and linguistic abilities of the preschool child when these abilities were analysed by "instrument ii". preschool children from 5 to 6 years old recently admitted ("r") to the program and those with more than 6 months of attendance ("a"), were tested and retested after 6 months. the first tests differentiated significantly between the two groups of children "a" x "r". the "re-test" after 6 months, shows that all the groups had progressed significantly but the groups of preschool children recently admitted ("r") to the program demonstrated greater progress than the group "a". the progress achieved was greater within the first six-month period than in the subsequent one. this perhaps suggests, that the activities of the guided recreation plan should be restructured in order to achieve more complex acquisition of abilities.
"Instrumento II" adicional de avalia??o do desenvolvimento de pré-escolares: seu valor na discrimina??o de grupos etários
Fernandes,José; Gandra,Yaro R.;
Revista de Saúde Pública , 1981, DOI: 10.1590/S0034-89101981000700011
Abstract: this battery of tests - the "instrument ii" - was selected in order to increase the sensitivity of the psychometric evaluations for children from 5 to 6 years old and designed to be used as a complementary resource for the former mechanisms - the "iadpe" and the "scale" both used on the ceape program. the present article studies the main statistical characteristics of the "instrument ii". it was found to increase the sensitivity of the psychometric evaluation of preschool children of the age quoted. a positive and significant correlation among the three methods mentioned was also obtained. on the basis of these results one can suggest that the "instrument ii" can be used as a complementary evaluation test for estimating the socio-psychological progress in preschool children of 5 and 6 years old belonging to low socio-economic classes.
Instrumento de avalia??o do desenvolvimento de pré-escolares dos Centros de Educa??o e Alimenta??o do Pré-Escolar
Fernandes,José; Gandra,Yaro R.;
Revista de Saúde Pública , 1981, DOI: 10.1590/S0034-89101981000700010
Abstract: selected items, with adequate sensibility to evaluate the eficacy of the ceape program with regard to the psycho-pedagogical development of preschool children were tested. these selected items together composed the "instrumento de avalia??o do desenvolvimento do pré-escolar - iadpe". the objective of this paper was to study statiscally the principal characteristics of that "instrument" evaluating its capacity of discrimination and comparing its results to those obtained on a "behavior scale" for preschoolers. the results show that the "instrument" correlated well with those of the "scale" and that it is a very useful and practical system for the evaluation of the psycho-pedagogical development of preschoolers.
Avalia??o de um roteiro simplificado de observa??o de pré-escolares em programas Centro de Educa??o e Alimenta??o do Pré-Escolar
Fernandes,José; Gandra,Yaro R.;
Revista de Saúde Pública , 1981, DOI: 10.1590/S0034-89101981000700013
Abstract: a survey to be came acquainted with the criteria used by teachers in classifying the preschool children was carried out. in continuation a simplified instrument with 15 selected items concerned with some aspects of the children's behavior and designed to be used by the teachers was organized. the results of analysis were compared with those obtained by more sophisticated mechanisms (iadpe, instrument ii and behavior scale) applied to the same children. the results show correlation to age but also show a constant improvement in behavior according to the length of time the children had attended the program. these results, even though preliminary indicated that the "observation card" (ficha de observa??o) could give the teachers good information and call their attention to some important aspects of preschool children's behaviour.
Avalia??o inicial dos efeitos psico-pedagógicos dos Centros de Educa??o e Alimenta??o do Pré-escolar
Fernandes,José; Gandra,Yaro R.;
Revista de Saúde Pública , 1981, DOI: 10.1590/S0034-89101981000700009
Abstract: the assessment of the socio-psycho-motor development of preschool children that participated in the ceape recreation program as compared to that of a control group of the same community, was carried out with the help of a set of tests prepared and pre-tested with that end in view. these preschoolers were also tested by the use of a behavior scale. in both areas of assessment ceape preschool children were seen to enjoy a considerable advantage over others. these results suggest that those children who do not attend ceape will probably face difficulties during their primary course.
